What is the value of x? _____ Units​

Mathematics
1 answer:
Vinil7 [7]3 years ago
4 0

Answer:

x=25

Step-by-step explanation:

The line QC makes:

           \triangle DQC\sim\triangle DBR

Using the property of similar triangles:

\dfrac{DQ}{BD} =\dfrac{DC}{DR} \\\\\dfrac{40}{40+24} =\dfrac{x}{x+15}\\

Using cross multiplication method:

40(x+15)=x(40+24)\\\\40(x+15)=x(64)\\\\40(x)+40(15)=64x\\\\40x+600=64x

Subtracting '40x' both the sides:

64x-40x=600\\\\24x=600

Dividing by '24' both sides:

x=\dfrac{600}{24} \\\\x=25

The value of 'x' in the figure is : x=25

A common inhabitant of human intestines is the bacterium Escherichia coli, named after the German pediatrician Theodor Escherich
grandymaker [24]
A.) P(t) = P0exp(kt)
P(20/60) = 40 exp(20k/60)
80 = 40 exp(k/3)
exp(k/3) = 80/40 = 2
k/3 = ln(2)
k = 3ln(2)

b.) P(8) = 40(2)^24 = 40(16777216) = 671088640 cells

d.) Rate of change = exp(8k) = exp(8(3ln(2)) = exp(24ln(2)) = exp(16.6355) = 16777216 cells / hour

e.) P(t) = 40(2)^3t; t in hours
1,000,000 = 40(8)^t
25,000 = 8^t
ln(25,000) = t ln(8)
t = ln(25,000)/ln(8) = 4.87 hours
